CVE-2026-53215

CVE-2026-53215 affects the Linux kernel mvpp2 driver: the RX path could return a descriptor buffer to the hardware Buffer Manager after it had been handed to XDP or an skb, allowing DMA into memory no longer owned by the RX ring. Root cause is improper handling of RX buffers in mvpp2_rx_refill() ...
